1. Choose the Right Font Size: While there's no one-size-fits-all answer, a font size of at least 14-16px for body text and 20-24px for headings is generally recommended.
2. Limit the Use: Overusing large fonts can make your email look cluttered. Use them sparingly to highlight key points and maintain a clean, professional look.
3. Consistency: Ensure that the use of large fonts aligns with your brand guidelines and overall design aesthetic. Consistency helps in building a recognizable brand identity.
4. Test Across Devices: Always preview your emails on multiple devices and screen sizes to ensure that the large fonts render correctly. This helps in maintaining a good user experience.
